Project Description

SEL-3505/SEL-3505-3 Real-Time Automation Controllers (RTACs)

SEL-3505 Real-Time Automation Controllers (RTACs)

Suitable for use in utilities and industrial environments, the SEL-3505/3505-3 Real-Time Automation Controllers (RTACs) are a lower voltage version of the SEL-3530 RTAC. The SEL-3505/3505-3 RTACs are compact and deliver all the standard features of an RTAC, making them excellent options for protocol conversion and secure communication when space is limited.

Integrated Security

Make the RTAC the secure access point into your substation or plant using LDAP central authentication, local role-based user authentication, access logs, and secure engineering access. This increases your system security and helps meet regulatory standards.

Simple, Seamless Configuration

Quickly design an integrated automation system that includes protocol conversion, SCADA communications, synchrophasors, time synchronization, data management, and programmable logic.

Renowned SEL Reliability and Support

The RTAC is designed and tested to meet or exceed IEEE 1613 and protective relay specifications for harsh environments, and to withstand vibration, electrical surges, fast transients, and extreme temperatures. The SEL RTAC operates reliably, even in challenging environments.

Custom Logic

Create your logic solutions in the embedded IEC 61131 logic engine, which comes standard with every automation controller. Build custom user logic and access all system tags, including diagnostics, contact I/O, protocol data, and communications statistics, to provide unparalleled control flexibility.
